FSB clerification!!

[MNGamer]

First off I have been referencing these forums for literally years, and I have always had my questions answered w/out posting. That being said I can not find an answer to this.

I thought about getting this CPU:

I want to put it on this mobo:
http://www.newegg.com/product/product.asp?item=N82E16813128059

The only reason I am asking this question is because of the difference in the fsb, will the board run at 800mhz? If this is not a good choice of boards for this cpu, could I be steered in a different direction. Things I plan on doing down the road but not right away is, OC'ing, then eventually upgrading to a quad core.

btw I will be getting this ram if it is relevant:

Thanks in advance

It should work fine.

 

[MNGamer]

Thanks NMDante,

I wasn't sure because the mobo doesn't list a fsb of 800.

Is this cpu a good one for o'cing? I mainly selected it because of the price.

Dante,
Just got back from 5 weeks in NM. Gourgeous. Spectactular. Breathtaking. People have no idea how magnificent the US countryside really is.

intel mobos, unlike nvidia unlinked and single single mhz adjstments, have only 3 rations and 3 strap settings - in the case of gigybyte you see 2:1 at the low end and 4:1 at the high - with 2:5:1 etc

so when you run a 800mhz chip you need higher ratios for ram

it can be confusing

i would suggest with an 800fsb chip you get ddr800 ram u see!

Thanks Dragonsprayer,

Then the ram I have selected should be fine I am assuming.

Yeah. I guess if you live somewhere long enough, the beauty gets lost. I took a trip down south, and remembered how nice this state is again.
Glad you liked it.

The CPU will work just fine in that board.
The CPU is an excellent OCing CPU.

Right from the Get-Go, you can try a simple OC.
Set the Memory to a 1:1 Ratio and the FSB to 533 which is the norm for most C2D chips.

This will give you a 2.9Ghz speed which is quite low for this chip.
It will also increase your FSB from the default of 400 which is a little low.

Thanks Zenmaster,

Again thanks to all you guys, I can't wait to finally upgrade from my Athlon XP.

You don't do FSB values as DDR. System Bus would be 200 -> 266. DDR2 Ram would obviously double that. Running DDR2800 @ 533 for 1:1 makes me want to cry. I'd venture to guess that 99.9% of Intel boards have it so you can run the DDR2800 at rated speed at 200, 266, and 333 Bus speeds.

 

[zenmaster]

Yes, you are correct. It would be 266 in the BIOS which runs the memory at DDR2-533 Speeds which results in an effective FSB of 1066.

However, changing the Memory Multiplier to get a faster FSB does not always yield better performance due to timing issues.

In addition, the Memory Multiplier greatly confused people when doing OCs and they inadvertently OC the memory as well.

When OCing, it's always best to start at 1:1 until you find a comfortable speed at which your system will run.

At that point, if you find that bus is running significantly different, you may want to try a memory ratio to get you memory running faster.
Howerver, even if you do this successfully, there is not guarentee of a performance boost.

Which is a reason why lots of folks suggest only DDR2-667 for many systems since DDR2-800 is overkill. However in my mind, with the price difference being so small, there is no point to not getting faster ram in the event he gets a new chips with a faster default FSB.

 

[zenmaster]

Here is an example of the effects of FSB on performance.
In these charts you will see the FSB speeds between 800 and 1280.

Despite a 50% difference between some of the speeds, the difference in results is quite minimal.

The important thing is to focus first on getting your CPU to a good level. Tweaking the memory and FSB settings will not get you very much at some point since the FSB is not a bottleneck.

A FSB of 1066 running DDR2-1066 is the default standard for the Q6600.
If it's not serioulsy huring the Q6600, then I'm sure his Dual running at slightly higher speeds will be fine.

I completely understand where you are coming from. And 1:1 will work just fine to get him start. I just don't think buying DDR800 and underclocking it to 533 MHz will help a whole lot!

 

[sprucebr1]

Yeah, the E4500 will be fine with that board. I have that exact board myself, and I know newegg say its 1066/1333, but if you check out the board on http://www.giga-byte.com it says that 800fsb is supported.
